So I tried my 54 at 75 yards. I used a 2'x2' piece of about 1/4" wood as a backing. Testing pellet drop(.22) and my results were as follows.
HN ftt roughly 9" drop.
Jsb exact jumbo match roughly 10" drop.
Surprised the crosman premier hp has only a 6" drop.
The crosman and H&N sounded like they hit the wood much harder than the jsb jumbos too.
All pellets blasted through the wood at 75 yards.
Some of the groups were darn good I think for using a cheap old 4x32 scope. All would be inside an apple. Slightly smaller some.
I tested penetration on a piece of solid maple hardwood floor scrap and it went in the depth of the pellet only. The skirt was flush with the wood. At only a foot away. Maple flooring is extremely hard though. My .22 mag will go through maybe 3 pieces at 100 yards though lol

Surprised the 14.3 hollow points had the least drop. I would have expected a heavier round nose would have been better. Don't remember the weight on the fft and jsb's but is interesting.

The Crossman pellets have a very high BC. They just fly well. I did some tests in the early 90's. My Diana model 48 and my R10 in .177 shot that pellet better, flatter, than any other
-
Read somewhere that the hollow point hole acted like a flat spot, causing more drag than a round nose and heavier pellets are suppose to retain their velocity because they should have a better BC.
Would be interesting to know what the muzzle velocity is of each one.
-
I was surprised too. I thought the same thing, that the hp front would create more drag. But all the shots were about 3.5-4" higher then the two others tested.
The crosmans fit much tighter in the bore too.

Thanks for sharing! Great down to earth review.

H&N FTT in .22 weigh 14.66 grains; JSB Exact Jumbo weigh 15.89 grains.

You're welcome.
What are some other pellets that may shoot great in my RWS 54?
Looking for ideas.
-
H&N and JSB are two of the best brands of pellet. I would try the RWS Super H Point if you are a hunter. I used them in an XS46U that I had (23 fpe in .22) and those pellets did damage!
-
What different jsb pellets are good? I have the jumbo match exact. What a mouthful. Does that just mean they are heavier then regular exact match pellets? I noticed H&N has a bunch of options as well
-
Bisley LRG shoot very well in my model 460. Repeatedly shoots nine out of ten shots under a nickel at 30 meters (100 feet).

I've never heard of bisley before. Good to know though. Thanks
